nsautolighting Fog Light Wiring Harness Kit (H11/H8/880/881) with 40A Relay & Switch for Toyota

Overview

Transform your fog lighting setup with the nsautolighting wiring harness kit, designed to simplify installation and upgrade possibilities for a broad range of Toyota models from 2005 to 2022. This kit pairs a robust 40A 12V relay with durable 16 AWG copper conductors, a flame-retardant housing, and an OEM-style push button switch featuring an LED indicator. It helps you route power cleanly to your fog lamps while keeping the vehicle’s wiring organized and protected, even in demanding weather conditions.

The system is built to support H11, H8, 880, and 881 fog lamps, with an extra-long pigtail that lets you place the switch and relay in a location that suits your interior and engine bay layout. A SPST (single-pole, single-throw) design provides straightforward on/off control and a safer power path, helping to mitigate voltage drop that can affect fog light performance.

What you get and how it helps

• Independently control fog lights, while preserving other lighting circuits for flexibility and safety.
• Extendable wiring to accommodate diverse vehicle layouts and preferred mounting spots.
• Pure copper core wires for reliable conductivity and reduced resistance.
• Protective, flame-retardant housing keeps wiring organized and shielded in the engine bay.

Compatibility and use cases

Designed for a wide array of Toyota vehicles, including models like Tundra, Tacoma, 4Runner, Land Cruiser, Sequoia, Sienna, Avalon, Highlander, RAV4, Prius, and more. It’s suitable for replacement fog light harnesses or as an add-on kit to enable separate fog lamp operation. Before ordering, measure the switch size to confirm it fits your vehicle’s center console panel and the fog light dimensions you plan to upgrade.
